有用于创建茎叶图的 pandas 功能吗

问题描述

是否存在与R的stem()函数等效的大熊猫，用于为数字Series创建茎和叶图?

Is there a pandas equivalent to R's stem() function for creating stem and leaf plots for a numeric Series?

我可以轻松编写一些代码，但是想知道我是否错过了精美的手册中的内容.

I could easily write some code but am wondering if I have missed something in the fine manual.
